Initial Post on GERD vs PUD Gastroesophageal Reflux Disease…

Initial Post on GERD vs PUD Gastroesophageal Reflux Disease Versus Peptic Ulcer Disease Both gastroesophageal reflux disease and peptic ulcer disease affect the gastrointestinal tract and are commonly confused with one another. While there are similarities between these two diseases, there are many distinct differences that must be considered. Gastroesophageal reflux disease (GERD) occurs when gastric content enters the esophagus and causes inflammation or irritation. This esophageal inflammation is called esophagitis, and it can be chronic or acute (Capriotti, 2024). Peptic ulcer disease (PUD) happens in the linings of the stomach and duodenum, as opposed to the esophagus. It causes these linings to erode because of the gastric acid that enters them (Capriotti, 2024). These two conditions are similar because they both involve damage caused by gastric acid, but I want to further explore the differences. Gastroesophageal Reflux Disease Etiology, Genetic Risk, Signs, and Symptoms The cause of GERD is the weakening of the muscle in the lower esophageal sphincter (Capriotti, 2024). Various medications or foods can cause the lower esophageal sphincter (LES) to weaken. When this sphincter weakens, it allows backflow of gastric acid into the esophagus. This causes protective layers of the esophagus to erode. Another factor that can cause GERD to worsen is gastroparesis. Gastroparesis happens when the passage of gastric content into the duodenum is slowed down (Capriotti, 2024). There does not seem to be any genetic risk factors attributed to GERD.  Although the signs and symptoms vary in GERD, the most common signals are heartburn and regurgitation. Treatment plans vary depending on which of these symptoms is more prevalent (Katz et al., 2022). Chest pain is another commonly seen GERD symptom that often goes along with other symptoms. Because these symptoms are fairly generic, it is not unlikely that GERD will be initially misdiagnosed. Another sign of GERD being present is when extraesophageal symptoms appear (Katz et al., 2022). The following are some examples of extraesophageal symptoms given by Katz et al. (2022): asthma, chronic cough, dental erosions, dysphonia, laryngitis, and sinusitis.  Diagnosis and Treatment The first step in GERD diagnosis is completing a simple questionnaire called the GERDQ. Following this, the best option to confirm a GERD diagnosis is endoscopy (Capriotti, 2024). An endoscopy allows the clinician to see inside of the esophagus and look for signs of gastric acid reflux damage. During the endoscopy, pH testing and manometry can be done. Testing of pH is very important in diagnosing the level of acid reflux, and manometry will determine the pressure ability of the LES (Capriotti, 2024).  The primary treatment for GERD is lifestyle changes. Capriotti (2024) lists these lifestyle changes as options to help GERD patients: eating small and frequent meals to prevent abdominal distention, not lying down for two to three hours following a meal, losing weight if obesity is present, and stopping smoking. If pharmacological measures need to be taken to help the patient, medications will be prescribed in order to prevent dysfunction of the LES. Improving functionality of the LES will prevent gastric acid from entering the esophagus and causing damage. Medications that fall into this category are antacids, proton pump inhibitors, and histamine-2 receptor antagonists (Katz et al., 2022).  Peptic Ulcer Disease Etiology, Genetic Risk, Signs, and Symptoms The three most common causes for peptic ulcer disease (PUD) according to Malik et al. (2023) are H. pylori infections, NSAIDs, and other medications. PUD causes inflammation and erosion of the linings in the stomach and duodenum by means of pepsin or gastric acid secretion (Malik et al., 2023). It is very common that ulcers form as a product of these lining erosions. In contrast to GERD, PUD does have a genetic risk factor. There is a genetic polymorphism that “delays the metabolism of several NSAIDs” (Capriotti, 2024). This delay increases the risk of ulcers forming.  There are many signs and symptoms of PUD. Some of these include unintentional weight loss, abdominal pain, bloating, and feeling abnormally full when eating (Malik et al., 2023). Nausea is also a common symptom, and hematemesis, which is the vomiting of blood, can occur. Another symptom is having blood in your stool; this is called melena (Malik et al., 2023). Hematemesis and melena are both related to gastrointestinal bleeding, which is a more urgent symptom. If these symptoms begin, the patient should seek care as soon as possible.  Diagnosis and Treatment The best path for diagnosis of PUD is endoscopy (Kim, 2025). This allows the ulcers and H. pylori infection to be viewed and confirmed. However, some patients with more severe symptoms may need to take alternate routes to get their diagnosis. In addition, according to Capriotti (2024), blood samples, urease tests, and fecal H. pylori antigen tests are often taken to test for H. pylori presence.  As far as treatment of PUD goes, it often begins with eliminating factors that could worsen the patient’s condition. It is important for the patient to stop NSAID usage if that is occurring, and getting rid of H. pylori infection is of the utmost importance. This can be accomplished through taking antibiotics and antisecretory agents (Kim, 2025). Capriotti (2024) says, “The choice of antibiotic is influenced by the patient’s genotype and strain of H. pylori.” In other words, the medicine that is prescribed will differ depending on the patient’s genetics and infection level. Proton pump inhibitors and histamine-2 receptor antagonists are other common medications that can assist in overcoming PUD (Malik et al., 2023). A lifestyle change that can greatly decrease the risk of PUD coming back is to avoid acidic foods and drinks (Capriotti, 2024).  The Similarities and Differences of GERD and PUD To conclude, I want to point out some of the major similarities and differences between GERD and PUD. The main similarity between these two conditions is that they are brought on by some sort of abnormality with gastric acid. However, the location where the acid causes its damage is different between the two disorders. In GERD, problems arise in the esophagus due to the LES weakening. In PUD, damage arises from H. pylori infection or damage from NSAIDs. Although ulcers can present themselves in GERD, they are much more common in PUD. Erosion of various organ linings occurs in both conditions, but they happen in different areas. GERD causes erosion of esophagus linings; PUD causes erosion of stomach and duodenum linings. A similarity in diagnosis is the importance of endoscopies to view the damage. According to Katz et al. (2022) and Malik et al. (2023), proton pump inhibitors and histamine-2 receptor antagonists are often prescribed for both GERD and PUD, but the differences in the overall target must be considered. A major part in treating GERD is fixing the weakness of the LES whereas in treating PUD, getting rid of H. pylori infection is necessary. Finally, I want to stress the importance of differentiating these two disorders in the health care field. Upon first glance, they may seem similar. However, diving deeper into diagnosing and treating these two conditions is paramount to the healing process of the patient. I hope that health care professionals take the differentiation of these two disorders seriously so that patients can have the best possible outcomes.  References Capriotti, T.
